while preparing packaging of upcoming rustc 1.27.0 (stable) for OpenBSD, I found it is not able to fully rebuild itself.

exactly, rustc-1.27.0 fails to build rust-installer tool, due to error-chain crate, due to unused_doc_comment has been renamed to unused_doc_comments lint error.

strictly speaking, rustc 1.27.0 is able to bootstrap itself. but the distributed tarball doesn't permit such bootstrapping. it is a niche problem that could affect downstream while packaging.

    There isn't much we can do without a new error-chain release. #51501

    Beyond switching rust-installer to failure of course :p.

    Why hasn't this been caught while 1.27.0 was in beta?

    @est31 it is failing in a specific configuration: rebuilding. bots are testing rustc-1.26.2 is able to build rustc-1.27.0, but not rustc-1.27.0 to be able to build rustc-1.27.0

    @semarie yeah but it should show up when 1.27.0 tries to build whatever is on nightly.

    @est31 here my analysis.

    currently nightly is build using 03fb2f4 . I downloaded a beta tarball pointed by https://github.com/rust-lang/rust/blob/master/src/stage0.txt#L15 and checked the version file.

    The rename unused_doc_comment to unused_doc_comments was landed later to beta branch in #51037.

    so if I didn't mess myself, it seems to me that the latest commit in the beta branch isn't used to build nightly. so not all changes are tested in beta.

    Oh that's unfortunate. Thanks @semarie for digging this up.

    Right so I see the following options:

    1. remove (parts of) Fix naming conventions for new lints #50879 from the beta (and stable) branch... one could argue that parts of it are a breaking change and thus should ride the normal trains
    2. don't pass -D warnings for the rust-installer crate
    3. patch the rust-installer crate to add #[allow(warnings)] or #[allow(renamed_and_removed_lints)] or something like that
    4. wait for a new release of error-chain and update to it
    5. update to a git version of error-chain... cargo-vendor should support git dependencies now IIRC

    This is indeed unfortunate (sorry about the problem here!) -- I think you should be able to fix this by changing config.toml to have deny-warnings set to false in the [rust] section.

    Passing deny-warnings=false in config.toml workaround efficiently the problem. And patching error-chain to add rust-lang-deprecated/error-chain#247 too.

    What needs to be done for this issue to be resolved?

    I think the recommended fix for this issue is #51650 (comment): it's not hard for downstream users to follow it, and it's too late for us to rebuild the tarballs of 1.27.0.
